PASSIVES RUECKHALTESYSTEM FUER EIN KRAFTFAHRZEUG

The invention relates to a motor vehicle passive restraint system comprising a gas generator for inflating an air bag attached thereto. The generator (10) comprises a mounting plate assembly (12) having a base plate, a recessed portion (18) for receiving and supporting a diffuser plate (22) and means for receiving and attaching the air bag (32). The mounting plate assembly is integrally constructed of a relatively light weight material capable of being stamped utilizing conventional stamping equipment. The generator additionally comprises a diffuser plate (22) with a plurality of gas exhausts (30). The diffuser plate (22) further comprises a support plate configured for connection to the recessed portion of the mounting plate assembly, and at least one integral side wall portion extending from the support plate. The diffuser plate (22) is connected to the mounting plate assembly (12) in a manner to permit a minimal degree of separation between the diffuser plate and the mounting plate assembly in the event the system becomes over-pressurized. Included within the generator is a gas generant composition. The mounting plate assembly and diffuser plate form a housing for this gas generant composition.
